A bakery has fixed costs for retail space, electricity, and appliances of $15,000. The variable cost of baking a cookie is 0.25
den301095 [7]

Answer:

Step-by-step explanation:

That $15,000 sounds like an annual amount, not a monthly or weekly amount.  In the absence of clarification of this, I will include that $15,000 in the following calculations:

Let the # of cookies baked be z and the number of cakes be k.

Then:

Total cost = $15,000 + ($0.25/cookie)z + ($3.53/cake)k

In this specific case, where the number of cookies is z and the number of cakes is k, the formula  

Total cost = $15,000 + ($0.25/cookie)z + ($3.53/cake)k

becomes ...

Total cost (z, k)  = $15,000 + ($0.25/cookie)(400) + ($3.53/cake)(200),

and this works out to:

TC (z, k) = $15,000 + $100 + $706 = $15,000 + $806 = $15,806.

No cakes or cookies could be good enough to warrant production costs that high!

Double-check to ensure that you have copied this problem down completely and accurately.

Mean: add all the values together and divide by how many numbers there are.
Example- 2+4+6+8+10=30
30/5=6. The mean is 6

Median: arrange the numbers in order from least to greatest (counting order). If there is more than one of any number make sure to put them all together. Then find the number in the middle. That's the median. If there isn't one number in the middle, take the two 'middle' numbers, add them together and divide by 2. That will be the median
Ex- 2, 4, 6, 8, 10 median is 6
Ex- 2, 4, 6, 8, 10, 12 6+8=14 14/2=7 median is 7

Mode: what number shows up the most often? Sometimes there might not be a mode if there are no repeated values.
Ex- 2, 4, 6, 6, 8, 10 the mode is 6, it is in the list more than any other number

Range: the difference of the greatest value and least value
Ex- 2, 4, 6, 8, 10 10-2=8. The range is 8
One thing that is the MOST helpful when finding all of these is to put all the numbers in counting order (least to greatest) before you try to do anything!

Sorry I can't be more specific, it's difficult to read the graphs and charts
